With all the announcements we had in June, it is easy for some of the more subtle enhancements to get overlooked. While I was at Orlando for the IBM Edge conference, I was able to blog about some of the key featured announcements. Then, later, when I got back from Orlando to Tucson, I was able to then blog about [More IBM Storage Announcements]. For IBM's Scale-Out Network Attach Storage (SONAS), I had simply:
"SONAS v1.3.2 adds support for management by the newly announced IBM Tivoli Storage Productivity Center v5.1 release. Also, IBM now officially supports Gateway configurations that have the storage nodes connected to XIV or Storwize V7000 disk systems. These gateway configurations offer new flexible choices and options for our ever-expanding set of clients."
In my defense, IBM numbers its software releasees with version.release.modification, so 1.3.2 is Version 1, Release 3, Modification 2. Generally, modification announcements don't get much attention. The big announcement for v1.3.0 of SONAS happened last October, see my blog post [October 2011 Announcements - Part I] or
the nice summary post [IBM Scale-out Network Attached Storage 1.3.0] from fellow blogger Roger Luethy.
Here is a diagram showing the three configurations of SONAS.
I have covered the SONAS Appliance model in depth in previous blogs, with options for fast and slow disk speeds, choice of RAID protection levels, a collection of enterprise-class software features provided at no additional charge, and interfaces to support a variety of third party backup and anti-virus checking software.
The basics haven't changed. The SONAS appliance consists of 2 to 32 interface nodes, 2 to 60 storage nodes, and up to 7,200 disk drives. The maximum configuration takes up 17 frames and holds 21.6PB of raw disk capacity, which is about 17PB usable space when RAID6 is configured. An interface nodes has one or two hex-core processors with up to 144GB of RAM to offer up to 3.5GB/sec performance each. This makes IBM SONAS the fastest performing and most scalable disk system in IBM's System Storage product line.
I thought I would go a bit deeper on the gateway models. These models support up to ten storage nodes, organized in pairs. The key difference is that instead of internal disk controllers, the storage nodes connect to external disk systems. There is enough space in the base SONAS rack to hold up to six interface nodes, or you can add a second rack if you need more interface nodes for increased performance.
SONAS with XIV gateway
XIV offers a clever approach to storage that allows for incredibly fast access to data on relatively slow 7200 RPM drives. By scattering data across all drives and taking advantage of parallel processing, rebuild times for a failed 3TB drive are less than 75 minutes. Compare that to typical rebuild times for 3TB drives that could take as much as 9-10 hours under active I/O loads!
In the configuration, each pair of storage nodes can connect to external SAN Fabric switches that then connect to one or two XIV storage systems. How simple is that? These can be the original XIV systems that support 1TB and 2TB drives, or the new XIV Gen3 systems that support 400GB Solid-state drives (SSD) and 3TB spinning disk drives. In both cases, you can acquire additional storage capacity as little as 12 drives at a time (one XIV module holds 12 drives).
The maximum configuration of ten XIV boxes could hold 1,800 drives. At 3TB drive per drive, that would be 2.4PB usable capacity.
The SONAS with XIV gateway does not require the XIV devices to be dedicated for SONAS purposes. Rather, you can assign some XIV storage space for the SONAS, and the rest is available for other servers. In this manner, SONAS just looks like another set of Linux-based servers to the XIV storage system. This in effect gives you "Unified Storage", with a full complement of NAS protocols from the SONAS side (NFS, CIFS, FTP, HTTPS, SCP) as well as block-based protocols directly from the XIV (FCP, iSCSI).
SONAS with Storwize V7000 gateway
The other gateway offering is the SONAS with Storwize V7000. Like the SONAS with XIV gateway model, you connect a pair of SONAS storage nodes to 1 or 2 Storwize V7000 disk systems. However, you do not need a SAN Fabric switch in between. You can instead connect the SONAS storage nodes directly to the Storwize V7000 control enclosures.
To acquire additional storage capacity, you can purchase a single drive at a time. That's right. Not 12 drives, or 60 drives, at a time, but one at a time. The Storwize V7000 supports a wide range of SSD, SAS and NL-SAS drives at different sizes, speeds and capacities. The drives can be configured into various RAID protection levels: RAID 0, 1, 3, 5, 6 and 10.
Each Storwize V7000 control enclosure can have up to nine expansion drawers. If you choose the 2.5-inch 24-bay models, you can have up to 480 drives per storage node pair, for a total of 2,400 drives. If you choose the 3.5-inch 12-bay models, you can have up to 240 drives per node pair, 1,200 drives total. At 3TB per drive, this could be 3.6PB of raw capacity. The usable PB would depend on which RAID level you selected. Of course, you don't have to limit yourself all to one size or the other. Feel free to mix 2.5-inch and 3.5-inch drawers to provide different storage pool capabilities.
All three SONAS configurations support Active Cloud Engine. This is a collection of features that differentiate SONAS from the other scale-out NAS wannabees in the marketplace:
Policy-driven Data Placement -- Different files can be directed to different storage pools. You no longer have to associate certain file systems to certain storage technologies.
High-speed Scan Engine -- SONAS can scan 10 million files per minute, per node. These scans can be used to drive data migration, backups, expirations, or replications, for example. It is over 100 times faster than traditional walk-the-directory-tree approaches employed by other NAS solutions.
Policy-driven Migration -- You can migrate files from one storage pool to another, based on age, days since last reference, size, and other criteria. The files can be moved from disk to disk, or move out of SONAS and stored on external media, such as tape or a virtual tape library. A lot of data stored on NAS systems is dormant, with little or no likelihood of being looked at again. Why waste money keeping that kind of data on expensive disk? With SONAS, you can move those files to tape can save lots of money. The files are stubbed in the SONAS file system, so that an access request to a file will automatically trigger a recall to fetch the data from tape back to the SONAS system.
Policy-driven Expiration -- SONAS can help you keep your system clean, by helping you decide what files should be deleted. This is especially useful for things like logs and traces that tend to just hang around until some deletes them manually.
WAN Caching -- This allows one SONAS to act as a "Cloud Storage Gateway" for another SONAS at a remote location connected by Wide Area Network (WAN). Let's say your main data center has a large SONAS repository of files, and a small branch office has a smaller SONAS. This allows all locations to have a "Global" view of the all the interconnected SONAS systems, with a high-speed user experience for local LAN-based access to the most recent and frequently used files.

Ten years ago, I travelled to New York City with my colleague, Randy Fleenor, to present the latest in IBM tape technology for the 50th Anniversary. On Thursday evening that week, the latest movie in the Star Wars saga, Episode II: Attack of the Clones was just released, and it was being shown using the new Digital Light Projection (DLP) technology just around the corner at the Ziegfeld theater! This movie was the first live-action film to be filmed entirely digital. George Lucas saw that digital video was the future, and started the process moving forward with this film.
I convinced Randy to join me, and we arrived at 11:10pm, the movie was scheduled to start at 11pm, so we figured we had only missed a few previews. We walked into a completely empty lobby. I asked for two tickets for the 11pm show at the ticket counter, and was told it was all sold out, and there was a huge line around the building for all the people waiting to see the 1:00am show, and that we might get in to see the 3:00am show.
Randy and I had meetings on Friday morning, so we were not going to wait in line all night to see a 3am show! Just then, a young man comes out of the theater. He said his girlfriend can't make it, and wanted a refund for his two tickets. I pulled out a twenty-dollar bill, offered to buy them directly at face value, and the theater employees approved the transaction. The seats were front row of the balcony section. By then we had missed all the previews and a short bit of the movie, but that was alright with us.
(FTC Disclosure: I am both an employee and stockholder in IBM. The U.S. Federal Trade Commission may consider this a paid, celebrity endorsement of LTO-5 tapes and the LTFS technology. References to other companies are for illustrative purposes and do not represent an endorsement of their products or services.)
Digital recording is ideal for all types of video, including movies, television, and commercial advertisements.
The latest excitement is over IBM's Linear Tape File System™ (LTFS), which IBM donated to the IT industry as open source so that everyone in the world can benefit. This allows tape cartridges to be treated like USB memory sticks, the ultimate in portability of data. It is supported for Windows, Mac OS, and Linux, and already well embraced by the Media-and-Entertainment (M&E) industry.
"The move to IBM technology has helped the network shrink its archive from 1,507 to just 388 square feet, representing dramatic systems and energy-cost savings."
"AlphaTV has been broadcasting since 1996, creating and storing all forms of video entertainment, from soap operas and documentaries, to movies and sporting events, and creating a vast video archive along the way. Initially, AlphaTV archived its programming on Sony Beta SP format video cassettes that stored up to 90 minutes of content. Not long after, in need of storage that offered greater density, it turned to DVCPRO format videos that stored up to 120 minutes. But even that format was not allowing the network to keep pace with its ballooning archive, a storage infrastructure that by 2011 spanned more than 1,507 square feet."
"'A Greek TV series stored on 100 DVCPRO tapes took up four shelves in our library, whereas on LTO-5 cartridge now takes up the space of a deck of playing cards,' Constantinos Colombus, chief technology officer at AlphaTV, said in a statement."
"IBM LTFS, an intuitive and graphical file system that provides direct access to data on LTO 5 drives, has enabled AlphaTV to manage, move and share video files much like they can with disk-management systems, by simply dragging and dropping. As a result, file management is easier to do and far more efficient, said Colombus."
To prepare for this anniversary, I spoke with Brad Johns, of [Brad Johns Consulting]. Brad was head of IBM tape marketing for a while, and ran tape customer councils to gather feedback from our largest customers. Brad was my mentor in marketing at IBM from 2003-2007 and has since retired from IBM to start his own consulting practice.
The comparison was made between Crossroad Systems' Strongbox® with Enterprise tape library, LTO-5 tapes using LTFS, versus a unified disk storage system offering NAS protocols on high-capacity 3TB drives. The findings: the tape-based archive had nearly 80 percent lower TCO than the disk-based solution!
You don't have to be in the middle of the Greek economy to real that is a good value!
Last week, on January 31, two of my colleagues retired from IBM. At IBM, retirements always happen on the last day of the month. Here is my memories of each, listed alphabetically by last name.
Mark Doumas retires after working 32 years with IBM. Mark was my manager for a few months in 2003. Back then, IBM was working on launching a variety of new products, including the IBM SAN File System (SFS), the IBM SAN Volume Controller (SVC), a new release of Tivoli Storage Manager (TSM), and TotalStorage Productivity Center (TPC), which was later renamed to IBM Tivoli Storage Productivity Center.
Mark was manager of the portfolio management team, and I was asked to manage the tape systems portfolio. I am no stranger to tape, as one of my 19 patents is for the pre-migration feature of the IBM 3494 Virtual Tape Server (VTS). The portfolio included LTO and Enterprise tape drives, tape libraries and virtual tape systems. My job was to help decide how much of IBM's money we should invest in each product area. This was less of a technical role, and more of a business-oriented project management position
Portfolio management is actually part of a chain of project management roles. At the lowest level are team leads that manage individual features, referred to as line items of a release. Release managers are responsible for all the line items of a particular release. Product managers determine which line items will be shipped in which release, and often have to balance across three or more releases. Architects help determine which products in a portfolio should have certain features. Since I was chief architect for DFSMS and Productivity Center, stepping up to portfolio manager was naturally the next rung on the career ladder.
(Side note: If you were wondering why I was only a few months on the job, it was because I was offered an even better position as Technical Evangelist for SVC. See my 2007 blog post [The Art of Evangelism] for a humourous glimpse of the kind of trouble I got in with that title on my business card!)
While my stint in this role was brief, I am still considered an honorary member of the tape development team. Nearly every week I present an overview of our tape systems portfolio at the Tucson Executive Briefing Center, or on the road at conferences and marketing events.
This year, 2012, marks the 60th anniversary of IBM Tape, but I will save that for a future post!
Jim is an IBM Fellow for IBM Systems and Technology Group. There are only 73 IBM Fellows currently working for IBM, and this is the highest honor IBM can bestow on an employee. He has been working with IBM since 1968 and now retires after 44 years! Jim was tasked with predicting the future of IT, and help drive strategic direction for IBM. Cost pressures, requirements for growth, accelerating innovation and changing business needs help influence this direction.
Many consider Jim one of the fathers of server virtualization. For those who think VMware invented the concept of running multiple operating systems on a single host machine, guess again! IBM developed the first server hypervisor in 1967, and introduced the industry's first [offical VM product on August 2, 1972] for the mainframe.
When I joined IBM in 1986, my first job was to work on what was then called DFHSM software for the MVS operating system. Each software engineer had unlimited access to his or her own VM instance of a mainframe for development and testing. This was way better than what we had in college, having to share time on systems for only a few minutes or hours per day. Today, DFHSM is now called the DFSMShsm component of DFSMS, an element of the z/OS operating system.
At various conferences like [SHARE] and [WAVV] we celebrated VM's 25th anniversary in 1997, and its 30th anniversary in 2002. Today, it is called z/VM and IBM continues to invest in its future. Last October, IBM announced [z/VM 6.2] release which provides Live Guest Relocation (LGR) to seemlessly move VM guest images from one mainframe to another, similar to PowerVM's Live Partition Mobility or VMware's VMotion.
Lately, it seems employees at other companies jump from job to job, and from employer to employer, on average every 4.1 years. According to [National Longitudinal Surveys] conducted by the [US. Government's Bureau of Labor Statistics], the average baby boomer holds 11 jobs. In contrast, it is quite common to see IBMers work the majority of their career at IBM.
The next time you have a tasty beverage in your hand, raise your glass! To Mark and Jim, you have earned our respect, and you both have certainly earned your retirement!
This week I was aboard the Queen Mary in Long Beach, California! This was a business event organized by [Key Info Systems], a valued IBM Business Partner. Key Info resells IBM servers, storage and switches.
The Queen Mary retired in 1967, and has been converted into a hotel and events venue. The locals just parked their car and walked on board, but I got to stay Tuesday through Thursday in one of the cabins. It was long and narrow, with round windows! There were four dials for the bathtub: Cold Salt, Hot Fresh, Cold Fresh, and Hot Salt.
Stepping on the boat was like walking back in time through history! If you decide to go see it, check out the [Art Deco bar at the front of the Promenade deck. The ship is still in the water, but is permanently docked. It is sectioned off to prevent the ocean waves from affecting it, so we did not have the nauseous moving back and forth normally associated with cruise ships.
(It is with a bit of irony that we are on the Queen Mary just days after the tragedy of the [Costa Concordia], the largest Italian cruise ship that ran aground near Isola de Giglio. The captain will have to explain how he [fell into a lifeboat] before he had a chance to wait for everyone else to get safely off the shipwreck. He was certainly no [Captain Sulley]! I am thankful that most of the 4,200 people survived the incident.)
Lief Morin, Founder and Chief Executive for Key Info Systems, kicked off the meeting with highlights of 2011 successes. I have known Lief for years, as Key Info comes to the Tucson EBC on a frequent basis. This event was designed to give his sellers an update of what is the latest for each product line, and what to look forward to in the next 12-18 months.
The next speaker was from Vision Solutions that provides High Availability solutions for IBM i on Power Systems. In 2010, their company nearly doubled in size with the acquisition of Double-Take, which provides data replication for x86 servers running Windows, Linux, VMware, Hyper-V and other hypervisors. The capabilities of Double-Take sounded similar to what IBM offers with [Tivoli Storage Manager FastBack] and [Tivoli Storage Manager for Virtual Environments].
Dinner at Sir Winston's
Rather than take the "Ghosts and Legends" tour, I opted for dinner at the Queen Mary's signature restaurant, Sir Winston's. This is a fancy place, so dress accordingly. If you want the Raspberry soufflé, order it early as it takes 30 minutes to prepare!
[Storwize V7000], including the new Storwize V7000 Unified configuration
Storage is an important part of the Key Info Systems revenue stream, so I was glad to have lots of questions and interactions from the audience.
Murder Mystery Dinner
The acting troupe from [Dinner Detective] put on quite the show for us! With all that is going on in the world, it is good to laugh out loud every now and then.
In other murder mystery dinners I have participated in, each person is assigned a "character" and given a script of what to say and when to say it. This was different, we got to pick our own characters. I chose "Doctor Watson", from the Sherlock Holmes series. Several attendees thought it was a double meaning with [IBM Watson], the computer that figured out the clues on Jeopardy! television game show, and has since been [put to work at Wellpoint] to help out the Healthcare industry.
After the "murder" happened, two actors portraying policemen selected members of the audience to answer questions. We didn't get a script of what to say, so everyone had to "ad lib". I was singled out as a suspect, and had fun playing along in character. One of the attendees afterwards said he was impressed that I was able to fabricate such amusing and elaborate responses to their personal and embarassing questions. As a public speaker for IBM, I have had a lot of practice thinking quickly on my feet.
Fibre Channel and Ethernet Switches
The next two speakers gave us an update on Fibre Channel and Ethernet switches, and their thoughts on the inevitability of Fibre Channel over Ethernet (FCoE). One of the exciting new developments is the [Brocade Network Subscription] which creates a flexible pay-per-use Ethernet port rental model for customers. This is especially timely given the Financial Accounting Standards Board proposed [FASB Change 13] that affects operating leases in the balance sheet.
With the Brocade Network Subscription, you pay monthly for the ports you are using. Need more ports, Brocade will install the added gear. Use fewer ports, Brocade will take the equipment back. There is no term endpoint or residual value like tradtional leasing, so when you are done using the equipment, give it back any time. This is ideal for companies that may need to have a lot of Ethernet ports for the next 2-3 years, but then plan to taper down, and don't want to get stuck with a long-term commitment or capital depreciation.
The last speaker was from VMware. IBM is the #1 reseller of VMware, and VMware commands an impressive 81 percent marketshare in the x86 virtualization space. The speaker presented VMware's strategy going forward, which aligns well with IBM's own strategy, to help companies Cloud-enable their existing IT infrastructures, in preparation for eventual moves to Hybrid or Public cloud deployments.
Special thanks to Lief Morin for sponsoring this event, Raquel Hernandez from IBM for coordinating my travel, and Pete, Christina and Kendrell from Key Info Systems for organizing the activities!
During lunch, people were able to take a look at our solutions. Here are Dan Thompson and Brett Cooper striking a pose.
Hyper-Efficient Backup and Recovery
The afternoon was kicked off by Dr. Daniel Sabbah, IBM General Manager of Tivoli software. He started with some shocking statistics: 42 percent of small companies have experienced data loss, 32 percent have lost data forever. IBM has a solution that offers "Unified Recovery Management". This involves a combination of periodic backups, frequent snapshots, and remote mirroring.
IBM Tivoli Storage Manager (TSM) was introduced in 1993, and was the first backup software solution to support backup to disk storage pools. Today, TSM is now also part of Cloud Computing services, including IBM Information Protection Services. IBM announced today a new bundle called IBM Storwize Rapid Application Backup, which combines IBM Storwize V7000 midrange disk system, Tivoli FlashCopy Manager, implementation services, with a full three-year hardware and software warranty. This could be used, for example, to protect a Microsoft Exchange email system with 9000 mailboxes.
IBM also announced that its TS7600 ProtecTIER data deduplication solutions have been enhanced to support many-to-many bi-direction remote mirroring. Last year, University of Pittsburgh Medical Center (UPMC) reported that they were average 24x data deduplication factor in their environment using IBM ProtecTIER.
"You are out of your mind if you think you can live without tape!"
-- Dick Crosby, Director of System Administration, Estes
The new IBM TS1140 enterprise class tape drive process 2.3 TB per hour, and provides a density of 1.2 PB per square foot. The new 3599 tape media can hold 4TB of data uncompressed, which could hold up to 10TB at a 2.5x compression ratio.
The United States Golfers Association [USGA] uses IBM's backup cloud, which manages over 100PB of data from 750 locations across five continents.
Customer Testimonial - Graybar
Randy Miller, Manager of Technical System Administration at Graybar, provided the next client testimonial. Graybar is an employee-owned company focused on supply-chain management, serving as a distributor for electical, lighting, security, power and cooling equipment.
Their problem was that they had 240 different locations, and expecting local staff to handle tape backups was not working out well. They centralized their backups to their main data center. In the event that a system fails in one of their many remote locations, they can rebuild a new machine at their main data center across high-speed LAN, and then ship overnight to the remote location. The result, the remote location has a system up and running by 10:30am, faster than they would have had from local staff trying to figure out how to recover from tape. In effect, Graybar had implemented a "private cloud" for backup in the 1990s, long before the concept was "cool" or "popular".
In 2001, they had an 18TB SAP ERP application data repository. To back this up, they took it down for 1 minute per day, six days a week, and 15 minutes down on Sundays. The result was less than 99.8 percent availability. To fix this, they switched to XIV, and use Snapshots that are non-disruptive and do not impact application performance.
Over 85 percent of the servers at Graybar are virtualized.
Their next challenge is Disaster Recovery. Currently, they have two datacenters, one in St. Louis and the other in Kansas City. However, in the aftermath of Japan's earthquakes, they realize there is a nuclear power plan between their two locations, so a single incident could impact both data centers. They are working with IBM, their trusted advisors, to investigate a three-site solution.
This week, May 15-22, I am in Auckland, New Zealand teaching IBM Storage Top Gun sales class. Next week, I will be in Sydney, Australia.
